Yes, it comes with 2 16 oz. single serve containers with lids. However you cannot get bigger cups for this model. They do not make them. Other models have 24 oz and some even 32 oz single serve cups you can purchase separately.

Probably not. The Ninja website does a good job of listIng which attachments are compatible with which motors. You could also take your containers to the store to see if it locks into their floor model.

Pahoh1,
Thank you for asking.This is dependent on the model of your unit, as no Nutri-Ninja blenders are created alike, so this might present a challenge in compatibility.
